Once you piss him off, Los goes ape — that’s how it’s gonna be, so you better get off your ass and deal with it.

Don’t piss him off — Los’ll go to war on your ass.

Thor is the Viking god of thunder and strength, and the dude wields a freaking huge hammer. Thor is also frequently associated with war and the apocalyptic “end-all war” called Ragnarok.

So, here, he’s saying that — when people piss him off — his mind gets all Thor-like: a war mentality.
Los’ll bring the hammer to battle, and finish it all.

He outlasts and outclasses everybody, lyrically.
He can also merk (slang for murder-kill) anybody, just using words.
Just like Buddha said: “The tongue is like a sharp knife … Kills without drawing blood.”

He feels so empowered — so “charged up” — that he could excrete power. This dude has so much “electricity” inside him, he could shit out a battery.

He’s saying that whoever comes at him — whoever thinks they’re better — is gonna get beat. They can’t even come at him cuz they’re so afraid, they choke.

He’s saying that what he’s done — his history — is world-record worthy, but follows up by saying that it’s nothing compared to what he can do.
Los making dis shit, man:

The phrase, out of this world, is a hyperbolic (exaggerated, man) idiom meaning “amazing” or “extraordinary."
So, he’s saying that he’s so amazing, so "out of this world” that (here, he’s taking the phrase literally) he’s got space stations harassing him.

Los is pretty damn high…

Here, he — again — references Yeezy and Jigga’s collaboration project, Watch The Throne. In the song, “Niggas in Paris”, Kanye closes up by rapping about “getting in his zone”.

(Yeah, you know, typical Kanye “Zone” pic…)
He’s just saying that he’s at his prime right now, and you definitely don’t want to mess with him.

He says the song’s title — “I’m On One."
This could be taken to mean he’s on drugs, which means he’s high.

Since he’s high, he’s up, right? This might mean that he’s above everybody else, so he’s better than everyone else… Yeah.
So, he’s essentially saying that he’s above everybody else, which isn’t surprising, cuz he’s young and strong.
